Python 扫雷游戏gtk3 点击后获取按钮值
Python minesweeper game gtk3 get button value after click
我使用 Gtk3 在 Python 2.7 中编写简单的扫雷游戏。使用 set_sensitive(False).
单击后，标签的显示值出现问题
第一种情况，我在点击后使用 button.hide()，效果很好，标签值显示出来了。
M - 船上有地雷
但我不想使用 hide()。单击 set_sensitive() 属性 后，我想阻止按钮。我尝试在 discover 函数 return self.button.set_sensitive(False) 中执行此操作，但之后我没有获得任何按钮值。我点击了所有板，所有按钮都被禁用。为什么我没有得到标签的任何价值？
使用后的板子set_sensitive(False)
我的代码：

怎么了？
隐藏按钮时，也会隐藏其标签。尝试禁用它：
button.set_state_flags(Gtk.StateFlags.INSENSITIVE, True)
用户将无法再次select此字段，您将确保标签显示正确。
问题是您在放置地雷时会创建新按钮。您似乎将这些新按钮放在了磁贴的背景中。因此，如果隐藏前景中的按钮，则只能看到带有标签（即背景）的按钮。
在这个修改后的版本中，我没有这样做，而是重复使用了现有的按钮。如果有地雷，我只是给他们贴上标签。我还在这些标签上使用了 set_no_show_all，这样当网格首次显示为 show_all 时它们就不会显示。然后，发现磁贴只是显示标签（如果存在）并禁用按钮的问题。
顺便说一句，我还通过连接到主 window 的 destroy 信号并调用 gtk_main_quit.
修复了退出应用程序的问题
